TO ALL WHOM 1T MAY CONCERN: l I

Be it known that I, CHARLES O. PIKE, lof North Lever-ett, in the county of Franklin, and State of Massachusetts, have invented a. new and improved Belt-F'nstener and Tightener; and I do hereby declare that tho following is a full, clear, and. exact description thereof, which will enuble those skilled in the art to make und use the some, reference being had to the accompanying drawings, forming part of this specification, in which-- K Figure 1 represents e. side viw of my improved belt-fastening and tightening-device, as applied to a. belt.

Figure 2 represents the tightening part detached, infront view. i

Figure 3 represents the fastening pnrt of the device when. attached to a. belt.

Figure 4 is a cross-section, teken in the linea: x, iig. 3.

Similar letters of reference indicute corresponding parts.

This invention relates to anew nud useful device for fastening the ends of abelt, and for tightening it, and the improvement consists in n clamp, for holding the ends of the belt together, and n lever-arrangement fitted to the clamp for tightening the belt, as hereinafter fully described.

-A half-collar, a, iig. 4, made of metal, of the width ofthe belt, is divided into spaces by partitions b b, on the inside, having T-shaped upper sides or heads, es seen in cross-section. The two ends of a, belt are slit intons many parts as there :ire spaces between the partitions b b, and being laid together, with their ends A A. in the same direction, the strips m m' are inserted between the partitions, and within the outer sides of the helfcollar a. The two ends A A of the belt, thus laid together, are fastened und held together by n clampingwedge, c, which extends across the upper side of the half-collar a, and is divided into teeth or prongs c', which iit within the collar and the spaces between the partitions Z7 b, under their T-shaped heads und over the belt, so

thnt when the lower end A of the belt is turned back upon itself, as shown in iig. 1, the collar sind wedge acting together cffectunlly prevent the ends A A( from slipping. In order to tighten the belt, two double levers, d d, el' d', are pivoted together at e e, the levers being connected, et one of their ends, by cross-bars 8 s', and at the other of their ends by bnrs g g'. One of the double levers is fitted within the other, as seen in iig. 2. Within the inside double lever d d is hung, by its ends, a. swing-bar, h, which is provided with a swinging handle, lc.

Thisdevice is operated by placing the connecting-bar s under the half-collar a, and between it and the lower end A et' the belt, and the connecting-bnr s, under the vupper end A of the belt, when, by moving the swing-bar h, so that it bears on the upper side of the end A of the belt, it will clamp upon the end, so that it can be drawn out from the collar a,V by spreading the double levers, as shown'in fig. 1. The connecting-bar s of the outside double lever d' d has its fulcrum at the foot, keeping the collar a and the lower end A' of the belt stationary. The clamping-wedge c will slip out at 'the same time, und, when the belt is tightened, must be replaced, to keep the ends fast,as shown in fig. 3.

Having described my invention, I claim as new, and desire to secure by Letters Patent- 1. The half-collar a and the clamping-wedge c, for fastening the ends of n belt, constructed and operating substantially as described.

2.4 The double levers d d', constructed and operating as described, in combination with the above fasteningdevice.
